STUMP OR STONE EXTRACTOR.

SPEOIFIGAIION forming part of Letters Eatent No. 684,077, dated October8, 1901.

Application filed December 7, 1900. Serial No. 39,035 (No model.)

To all whom it may concern.-

Be it known that I, ERIC MAROHAND, a subject of Her Majesty, the Queenof Great Britain, residing at St. Prime, in the county of Ohicoutimi,Lake St. John, Province of Quebee, Canada, have invented certain new anduseful Improvements in Stump and Stone Extractors; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in stump and stone extractors; andthe object in view is a simple and powerful extractor which can bereadily hauled from one place to another, adjusted over the object to belifted, and operated either by horse-power or by manual effort.

With these ends in view the invention consists in a stump and stoneextractor embodying novel features of construction, as will behereinafter fully described and claimed.

In the drawings hereto annexed, forming a part of this specification,Figure 1 is a side elevation of a machine embodying my invention. Fig. 2is a plan view thereof. Fig. 3 is a detail cross-section on the line 3 3of Fig. 2.

The same numerals of reference denote like parts in each of the severalfigures of the drawings.

The operating parts of my machine are all mounted on a portable frame,which is indicated in its entirety by the numeral 5. In the preferredconstruction shown by the accompanying drawings this frame consists ofthe pair of converging uprights 6 7, the inclined front upright 8, thesubstantially horizontal beams 9 10, the rear braces 11 12, the rearcross-bar 13, and the front brace 14. The lower ends of the uprights 6 7are united with the corresponding ends of the braces 11 12 to an axle 15through the medium of suitable bolts, said axle being equipped withsuitable carrying-wheels 16. Said rear braces 11 12 are joined by thecross-bar 13, which also connects the rear ends of the horizontal beams9 10, the latter diverging laterally from their front ends to the rearends. Said beams extend between the uprights 6 7 ,while the otherupright 8 is disposed between the beams, all these parts being firmlyjoined together to produce a frame which is braced at all points ofstrain. The front brace 14 connects the lower end of the upright 8 andthe front ends of the beams,.and this front part of the frame rests upona ground-shoe 17, the latter being connected loosely by a bolt, as at18, to the foot of the upright 8. It will be noted that the rear part ofthe frame is mounted on the carrying-wheels and the front parton theshoe, thus rendering the apparatus portable. The shoe is equipped withthe draft-hook 19, adapted for the attachment of a whififletree, wherebythe apparatus may be hauled across a field.

20 designates a sheave which is journaled on a suitable arbor in thespace between the upper ends of the converging uprights 6 7, and to theother upright 8 is pivoted a clevis 21. A lifting-chain 22 has one endattached to this clevis and leads over the sheave 20, so as to form abight, in which is arranged a traveling sheave 23, the latter restingupon the chain and equipped with a depending clevis 24, in which isadjusted or engaged the chain 25, that is adapted to be fitted aroundor'otherwise engage with the object to be lifted, such object being inthe form of a treestump, a heavy stone, or any other object of weight.

26 designates a pair of parallel track-bars which'are arranged withinthe frame in inclined positions, the upper portions of said track-barsbeing firmly secured to the uprights 6 7 or to the horizontal beams,while the lower ends thereof are bolted to the axle 15. Said track-barsare provided in their op- 32 designates a stationary pulley-blockprovided with a series of sheaves 33, and this pulley-block is securedfirmly in place between the track bars at the lower ends thereof.

34: is a haulage-cable which is rceved around the sheaves 31 of thetraveling pulley-block and the sheaves 33 of the stationary pulleyblock,one end of said cable being attached to a stationary eyebolt 35 on thefixed pulleyblock, while the other end of the cable leads away from theapparatus, so that a whiffletree may be connected thereto, thus adaptingthe cable to be hauled by horse-power, although two or more men may pullthereon, if desired.

It will be understood that the lifting-chain 22 has one end connected tothe clevis 21 on the frame, while the other end of said chain isattached to the link of the traveling pulley-block. 7

It is thought that the operation and advantages of the apparatus will bereadily apparent from the foregoing description taken in connection withthe drawings.

Changes within the Scope of the appended claims may be made in the formand proportion of some of the parts, while their essential features areretained and the spirit of the invention is embodied. Hence I do notdesire to be limited to the precise form of all the parts as shown,reserving the right to vary therefrom.

I claim- I 1. A stump-extractor comprising a suitable frame, paralleltrack bars secured firmly thereon and provided with guideways, atravcling pulley-block having suitable projections fitted slidabl y insaid guideways, a stationary pulley-block, a lifting-chain connectedwith the frame and with the traveling pulley-block, and a haulage-cablefitted to said pulley-blocks to form a multiplying connection therewith,substantially as described.

2. A stump-extractor comprising a frame having a wheeled axle at one endand a loose shoe at the other end, track-bars secured firmly to theframe and provided with guide ways, a pulley-block secured in astationary position at the lower end of the track-bars, a slidablepulley-block engaging with the guide ways, a lifting-chain connected tothe frame and to the slidable pulley block, suitable sheaves for saidchain, and a haulage-cable, substantially as described.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

ERIC MARCI-IAND.
